This On-Line-Series is an uninterruptible power supply incorporating double-converter technology. It provides perfect protection specifically for
Novell, Windows NT and UNIX servers.
The double-converter principle eliminates all mains power disturbances. A rectifier converts the alternating current from the socket outlet to direct current. This direct current charges the batteries and powers the inverter. On the basis of this DC voltage, the inverter generates a sinusoidal AC voltage, which permanently supplies the loads.
Computers and periphery are thus powered entirely by the mains voltage. In the event of power failure, the maintenance-free batteries power the inverter.
This manual covers the UPS listed as follows. Please confirm whether it is the model you intend to purchase by performing a visual inspection of the

50Hz and 60Hz. The bypass state could be set to enable and disable. The operating mode of UPS could be set between the Line mode, ECO mode and
Converter mode. Battery string could be set to one to night groups. Two Load segments could be set to on and off.
In bypass or no output mode, pressing the “Enter” button on the LCD panel for more than one second to enter setting mode. The LCD display is shown in the following diagram. The string “OPV” indicates that the current setting is output voltage. “230Vac” indicates the current default output voltage is 230Vac. if you want to set output voltage, press the “Enter” button for more than one second, a flickering string “208” would be shown, if the “Enter” button is pressed again, the string “208” turn to flickerless, the output volt is changed to 208V; if the
“Select” button is pressed for more than one second, the next flickering string
“220” appear, the order of flickering string is 208 – 220 – 230 – 240 – 208,
Press “Enter” button to confirm the output volt what you want.
Exit the setting mode to short touch the “Enter” button; continue setting to press “Select” button. if no any pressing on the “Select” or “Enter” button lasting for more than 10 seconds, the setting mode exit automatically.
The output frequency string “OPF”, Bypass status string ” bYPA”, operating mode string “MOdE”, Battery string “bSTR”, Load segment string “LS1” and
“LS2” would be presented circularly. The only one voltage value could be selected in “208V”, “220V”, “230V”, “240V” at any time; The only one frequency value could be selected in “50Hz”, “60Hz” at any time; Bypass status could be selected in “000” or “001”(Here 000 means Bypass
Disable,001 means Bypass Enable),The UPS would turn to bypass mode in
28 several seconds after “Bypass Enable” is selected, and turn to no output mode in several seconds after “Bypass Disable” is selected; Operating mode could be selected in “UPS”, “ECO”, “CVF”(Here “UPS” means the normal inverter mode, “ECO” means the high efficiency mode, and “CVF” means the converter mode), The mode change would be active only after the UPS is turned on;
Battery string could be selected in “001” to “009”(Here “001” means one group battery). Load segment 1 could be selected in “000” or “001”(Here 000 means load segment 1 off, 001 means load segment 1 on); Load segment 2 is the same as Load segment 1.
■
Here is a example for changing the Operating mode from normal mode to converter mode through the LCD panel.
Step 1: “OPV” after pressing the “Enter” button; Step 2: “OPF” after pressing the “Select” button.
Step 3: “bYPA” after pressing the “Select” button; Step 4: “MOdE” after pressing the “Select” button, press the “Enter” button to set mode, then “UPS” flickering;
Step 5: “ECO” flickering after pressing the “Select” button; Step 6: “CVF” flickering after pressing the
“Select” button again. Press the “Enter” button to make sure to change the mode. Short touch “Enter” button to exit setting mode.

To establish communication between the UPS and a computer, connect a computer to one of the UPS communication ports by using an applicable communication cable.
NOTE:
Only one of the communication ports can be active at one time. The USB port has priority over the RS-232 port.
When a communication cable is installed, the power management software can exchange data with the UPS. The software polls the UPS for detailed information on the status of the power environment. If a power emergency occurs, the software initiates the saving of all data and an orderly shutdown of the equipment
34
The RS-232 port is available for UPS monitoring, control, and firmware updates. To establish communication between the UPS and a computer, connect one end of the serial communication cable that comes with the UPS to the RS-232 port on the UPS. Connect the other end of the serial cable to the
RS-232 port on a computer.
The cable pins for the RS-232 communication port are identified in the following illustration.
